-- Vizio officially launched its P-Series 4K TVs last night, which start at $999 for a 50-inch set and go up to $2,499 for a 70-inch set — the first mainstream 4K TVs to be that aggressively priced. To celebrate, the company held a party in a New York art gallery, where the TVs were showcased playing high-resolution video art and in side-by-side comparisons to Samsung's 8500 series, which lists at $2,199 for a 50-inch set. "It's not only shipping an amazingly-priced 4K TV, but one that blows the competition away on picture quality," Vizio CTO Matt McRae told me.
